The Super League is set for a massive final week with all four teams separated by just one win.
With a 5-3 win over the Wasps, the Carp are now in first place with 12 points, clinching their finals berth.
They could finish anywhere from first or third, though, with the Clippers and Crushers tied on 10 points and the Wasps nine.
In the final found the Clippers and Carp play off for an automatic grand final berth while the Wasps and Crushers are in an elimination final.
GAME ONE: CARP 5 def. WASPS 3
For five-and-a-half innings it looked like the JSR Wasps (3-4) were on their way to a relatively cruisy win, but a last-gasp comeback by the Carp (4-3) in the sixth saw the fighting fish secure their finals berth with a 5-3 victory.
Mason Clavell was the Highway Player of the Game with the winning RBI in the sixth, as the Carp fought back from 3-0 for their fourth win of the tournament.
It was all yellow as the Wasps scattered their hits and runs, led by a pair of hits from Stefan Welch, Mitch Lightbody and Austin Gallagher.
The trio packed a punch while the Carp looked sluggish.
Wasps starter Jackson Brebner-Russ was their best on the mound with a pair of strikeouts from his two innings, American Matt Rabe backing him up with another two scoreless frames.
With a definite place in the grand final on the line the Carp, relief pitcher Wilson Lee helped them escape a pair of tight jams in the fifth and sixth, including loaded bases.
A comeback still looked unlikely, though, until they started to string together walks and hits in the bottom of the sixth.
That inning would ultimately be the final one as time became a factor and the likes of Josh LaPiana, Ryan Broome and Mason Clavell made solid connections.
Teenager Blake Farr continued his impressive tournament with three hits, while Clavell’s was arguably the most important with the sides tied at 3-3.
The catcher brought home two runs with a tidy single, helping the Carp complete a shock comeback.
GAME TWO: CLIPPERS 6 def. CRUSHERS 2
After pitchers dominated the first four frames another comeback was on the cards as the Dunmark Crushers (3-1-3) fought back from 2-0 down in the sixth, before the Clippers (3-1-3) claimed an emphatic 6-2 victory.
Five of their runs were unearned with Dakota Thompson and Griffen Weber scoring from loaded bases on a wild throw to first.
Dylan Brammer and Theo Lakmeche survived on the same throw and the pair scored thanks to a clutch single from Terrell Joyce.
Thompson and Weber finished with two hits each while Crushers Ben Andrews and Matt Hutchings had a pair.
Starters Tim Day and Jordy Grose were relatively unchallenged for their respective sides, the game’s first run came in the fifth inning.
It was a tidy double-blow for the Clippers with runs in the fifth and sixth, hits from Dakota Thompson and Dylan Brammer doing the damage.
Two runs were only a small buffer, though, and in the sixth Hutchings combined with Cresswell to score the Crusher’s first run.
Landon Hernandez then tied it up with his RBI single and you could you could cut the tension with a knife when Connor Hill struck out Nick Talbot with loaded bases.
Setting sail the Clippers loaded the bases in the seventh, capitalising on poor fielding to score four runs with two outs and runaway with the W, keeping their finals chances alive ahead of next week’s must-win if they want to finish in first place.
